Does the problem go away when you switch tanks? I Ha a similar issue, the inside of my rear tank had filled up with rust, shower head was broken, lines were clogged with rust.

When I pulled the fuel filter out and drained it, the amount of rust that came out was disgusting.

I ended up just replacing all my lines anyway since I found a leak in one of them.

I replaced both fuel tanks as well with polyethylene tanks but I regret very much not getting the 38 gallon rear tank and delete the transfer valve. If I had known the 38 gallon tank existed, I definitely would have done that.

@Lumberjackchuck my bigger problem was the fuel selector valve/air intrusions. Front tank at least was not really rusty at all, the rear tank looks fine front the outside. I’m still using it as I imagine the plastic pieces won’t make it through a filter and seems to sit at the bottom anyways.
